CHURN.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed September 16, 1907. Serial No. 393,091.

To all whom it may concern:

Be it known that I, DANIEL IV. MoNEEL, a citizen of the United States,residing at Charleston, in the county of Coles and State of Illinois,have invented certain new and useful Improvements in Churns, of whichthe following is a specification.

In the drawing, Figure 1 is a front elevation of my improved churn,parts being in section; Fig. 2 is an enlarged detail vertical sectionthrough the churn proper.

1 represents a suitable receptacle adapted to hold milk.

2 is a cylinder constructed of any suitable material, preferablyaluminum, at the bottom of which are a series of radiating orts 3extending through the wall of said oy inder.

4 is an annular flange secured to the cylinder above the ports 3, fromwhich depends an annular flange 5, said annular flange extending belowthe ports 3. The cylinder is provided with a cap 6 having a dependingannular flange 7, provided with a series of ports 8 positioned above theshoulder 9. The shoulder 9 rests upon the top edge of the cylinder 2.Secured to the cap 6 are two standards 10.

11 is an annular flange depending from the lower ends of the standards10 and surrounding the cap 6. This flange extends below the ports oropenings 8 in the cap.

12 is the churn dash adapted to slide through the journaled bearing 13formed in the cap 6. The upper end of the stem of the churn dash isforked as at 14, to which is pivoted a pitman 15 by means of the pin 16.

17 is a crank ournaled in the standards 10 to which is ournaled theupper end of the pitman 15.

18 is a hand operated crank secured to the shaft of the crank 17.

The cap 6 carrying the standards 10 is secured to the cylinder 2 bymeans of the bayonet joint 19. Any suitable means of securing the cap tothe cylinder 2 may be employed.

20 is a sup lemental dash secured to the stem 12 outsic e of and abovethe cylinder 2.

The operation is as follows, it being assumed that the cylinder 2 isimmersed in milk in the receptacle 1: The crank 18 is operated, therebyraising and lowering the dash 12 within the cylinder 2, which results inalternately drawing the milk in one set of ports and forcing it out atthe other set of ports in the cylinder. For instance, as the dash isbeing raised, milk is drawn in through the ports 3 and forced outthrough the ports 8. The milk on being forced through the orts in thecylinder and in its cap strikes the flanges 5 and 11, which are spacedsome short distance from the sides of the cylinder. By throwing the milkagainst these flanges with great force, the globules of milk or creamare broken up, thus facilitating the separation .of the butter. As soonas the butter is separated, it will float to near the top of the milkand the dasher 20 tends to gather the butter together and compact it inone body instead of separate globules.

The stroke of the dash 12 is such that it will not pass between theperforations and the top of the cap 6 and the perforations and thebottom of the cylinder 2. The reason for this is that if the dash wereallowed to press against the top or on the bottom of the cylinder as thebutter formed, it would compact the butter against the ends of thecylinder and in a short time clog the perforations, and prevent the flowof the milk through them. I find that butter formed outside of thecylinder by striking against the flanges 5 and 11 is constantly Washedaway from the cylinder by the milk and has a tendency to collect abovethe cylinder. A further object of the flanges 5 and 11 is to preventsplashing of the milk outside of the receptacle 1.

The receptacle 1 and its associated parts may be rigidly secured to thecylinder 2 by any suitable means.

What I claim is 1. In a churn, the combination with a cylinder havingducts leading therefrom at the top and bottom, flanges surrounding thecyl inder at the top and bottom, and extending to a point below saidducts, and a dash suitably mounted in said cylinder.

2. In a churn, the combination with a receptacle, of a cylinderpositioned therein and provided with ducts leading from the interior ofthe cylinder-at the top and bottom thereof, flanges extending over saidducts, but spaced from the side of the wall, and a dash mounted in saidcylinder.

3. In a churn, the combination with a receptacle, of a cylinderpositioned therein and provided with ducts in its wall at the lower endthereof, an annular flange surrounding said cylinder, but spacedtherefrom and ex tending below said ducts, a cover for said cylinderhaving radial ducts, a depending flange secured to said cover andextending below said ducts.

4. In a churn, the combination with a receptacle, of a cylinderpositioned. therein and provided With ducts in its wall at the lower endthereof, an annular flange surrounding said cylinder, but spacedtherefrom and extending below said ducts, a cover for said cylinderhaving radial ducts, a depending flange secured to said cover andextending belowsaid ducts, a reci rocating dash mounted in said cylinderanc extending above the cover, and a supplemental dash mounted upon thefirst-named dash outside of the cylinder above the cover thereof.

5. In a churn, the combination of a receptacle, of a cylinder removablysecuredthere in and provided with radiating ducts through its well atthe bottom, an annular flange surrounding the lower end of the cylinderbut spaced therefrom and depending below the said ducts, a cap for saidcylinder having radiating ducts, an annular flange depending from saidcap to a point below the said ducts in the cap, a dash reciprocallymounted in said cylinder, a stem secured to said dash and extendingthrough the cap, a supplemental dash secured to said stem above saidcap, standards extending from said cap, a crank shaft journaled betweensaid standards, a pitman connecting said crank shaft and the stem of thedash, and. a crank arm secured to said crank shaft.

The foregoing specification signed at Charleston, Illinois, this tenthday of August, 1907.
